Launched on 30th July 2020, Perseverance rover has successfully landed on the मार्च surface at Jezero Crater on 18th February 2021, after पृथ्वी से लगभग सात महीने की यात्रा। बनाया गया विशेष रूप से चट्टानों का नमूना एकत्र करने के लिए, Perseverance is the biggest and the best rover ever sent to मार्च. The sample catching system of the rover is one of most complex robotic system ever made. मार्च once had water on its surface, suggesting primitive microbial organisms may have lived there in the past. In view of the detection of methane gas in the atmosphere of मार्च in the recent past, there is a possibility of some form of microbial life being present even today. It is thought that the samples collected by the rover may have signs of life. However, this is one way trip of the rover to the मार्च and the samples collected will be brought back to the Earth using future missions. The samples will then be analysed for the confirmation of ancient form of life on the मार्च. Interestingly, the rover is carrying Ingenuity, a small helicopter that will explore areas like cliffs and craters where the rover cannot go.
इससे पहले कि बहुत देर हो जाए, पृथ्वी को छोड़ दो, Carl Sagan had once warned in view of remote possibility of Earth being hit by an asteroid in future just the way it was 65 million years ago when dinosaurs were eliminated. It may be reasonable to think that the future of humanity lies in becoming अंतरिक्ष-faring species, in becoming a multi-ग्रह species. And, here is an infinitesimally small step in that direction towards exploration of अंतरिक्ष for a better understanding of habitable world 1.
RSI मार्च घुमंतू दृढ़ता with its sophisticated robotic system specially designed to collect samples has successfully touched down on the मार्च surface at Jezero Crater. This place was once was a water lake that may have nurtured primitive life forms on मार्च. The robotic system of the rover will serve as eyes and arms of mankind for exploration on मार्च when it is not possible at this juncture to send astronauts. The मार्च 2020 Mission will set up a series of missions in future for bringing the collected samples to Earth for analysis 2.
मार्च once had a thick atmosphere that retained enough heat for water to remain in liquid state enabling running rivers and lakes on its surface. This suggests that primitive microbial life forms may have existed on मार्च. But, unlike Earth, मार्च unfortunately does not have a magnetic field to provide protection against powerful सौर पवन and ionising radiations. As a result, it lost its atmosphere to अंतरिक्ष in due course and the climate of मार्च changed to inhospitable frozen desert with a very thin atmosphere of today 3.
The key brief of this मार्च 2020 mission is to search for the signs of ancient microbial life that may have existed on मार्च before its climate changed to cold desert. Interestingly, in view of the detection of methane, it is postulated that some primitive life form may be present on मार्च even today. However, it requires confirmation because methane may be released from non-living sources as well.
Some of cutting-edge instruments that will play a key role in this are SHERLOC and PIXL. Few others will help the rover to collect data from a distance. It is pertinent to note that the rover has touched down on the Martian surface at Jezero Crater, which was a water lake in the past making it a high potential area to support microbial life forms. The rover is also collecting data about the past climate and geology of मार्च.
Not to miss the fact that this मार्च mission is not a round trip to Earth. The samples collected by Perseverance will potentially be delivered to a planned lander in future which will bring the samples to the Earth for analysis to condirm the existence of ancient form of life on मार्च.
Importantly, Perseverance is carrying several instruments and technologies whose successful use in data collection and exploration on this mission, will pave the way for future missions to the Moon and the मार्च 4.
